(01. 24-200) Thisinvention relatesto improvements in slide ends of the cut-metal edge 1the metal at these buckles and more particularly to'slides that arepoints is so formed (following the cutting procadapted for use inconnection with a longitudiess) as to provide ofi-set stop-projections 8nally folded strap threaded therein to provide a adapted to engageadjacent rigid cut-metal 5 loop below theslide from which a metal buttonedges 5A of the sheet body I for the purpose of 5 loop may be suspended,arresting the tongue 6 so that it cannot be forced The objects of thisinvention are to provide a out of the plane of the face 2 in thedirection slide buckle with a strap-binding element havof the interiorof the marginally cupped formaing a more uniform binding grip regardlessof tion of the sheet body I. The off-set projection the particularthickness of the strap threaded 8 as exaggeratingly illustrated by theFigure 6 10 therein, and to provide a slide buckle with strapis ofconventional form only but, with a sufthreading apertures of which oneis normally of ficient gauge of metal, a proper forming stroke lessshort diameter than that of the other, but adjacent both edges of; araised tongue 6 should having a yielding strap-binding element capableso spread and form the metal at these points ofadjusting the aperture;to receive therein a as to provide suificient projections 8. Instead 15strap of any thickness that can be passed of providing the tongue 6withthe stops 8, propthrough the other aperture. er stops 5 5 might justas well be. provided In the accompanying drawing the Figure 1 is by themetal of the body at the converging open a face view of the improvedslide; Figure 2 is cuts 5 5.

Thus the wedged contact cerned thebody may retain its fiat condition as of edge 7 0f the tongue 5 With theoubled 0 when cut, from the heet material.

At both strap with which its edge 1 contactsand, if the doubled strap thereby is sufilciently crowded into theaperture 4, the off-set projections 8 engage their adjacent edges 5A andhold the tongue 6 against swinging out of the plane of the face 2 of thesheet body I toward the cupped interior of the slide buckle.

From the foregoing it will be recognized that the improvement herein setforth provides a slide buckle with a novel strap binding element that isadapted for self-adjustment in its application of a substantiallyuniform grip upon a strap threaded into the slide without any specialregard to its particular thickness. Of course the applicant is aware ofthe previous art which discloses spring tongues integral with thestructure but, in each instance, the tongue there shown abuts a barseparated therefrom only by an open out such as appears upon either sideof the tongue. If it were not for the aperture' l located above the edgeI of the tongue 6 a strap of any great thickness would so deflect anddis"- tort the forced positionof the tongue G-that that portion of thestrap 'lyin'g'over'the tongue 5 would be so projected and humped astobe'obje'cti'onable to the wearer.

I claim:

1. A slide buckle comprising a' sheet-metal structure, cut-metal edgedapertures in a common plane and of different widths with which thestructur'eis' provided for' threading a strap therethrough, companionopen cuts intermediate the apertures and communicating with the apertureof lesser width to provide a resilient strap-binding element integralwith the structure and normally withinthe plane of the aperstructurehaving a rectangular margin receding from the plane of the sheet-metalto provide a rigid frame, spaced and parallel cut-metal edged aperturesof difierent widths with which the structure is provided in the plane ofthe sheetmetal for threading a strap therethrough, companion open cutsintermediate the apertures and communicating only with the aperture ofthe lesser width to provide a resilient strap-binding element in theplane of the apertures and integral with the structure, a cut-metal edgeof one of the apertures providing the strap-binding edge of theresilient element, and stop means provided by the structure adjacent theopen cuts to arrest the swinging movement of the resilient element outof the plane of the apertures in one direction;

3. A slide buckle compnising a sheet-body frame, a pair'of apertures ina common plane providedby the frame, a resilient tongue element'integralwith the frame and normally presenting a straight edge to, and therebydetermining the width of, one of the apertures, and stop means withwhich the buckle is provided to arrest the movement of the tongue edgeout of the plane of the apertures in one direction.

4. A slide buckle comprising a one-piece sheet-metal structure, a flatface with which the stru'cture'is provided, a rearwardly recedingmarginbounding said face, a pair of spaced upper and lower apertures ina common plane and extending across said face to provide openings forthreading from the rear a strap therethrough, a tongue integral with thestructure intermediate said apertures, the free extremity of the tonguebeing normally at rest in said plane within, and determining the widthof, the upper aperture, and means by which in the insertion of a strapinto said upper aperture from the rear the deflection of the freeextremity of the tongue is limited to a forwardly direction out of saidplane.
